In a world where Jabari returns...
...and there is world peace, no hunger, and a pony for every child, I believe the line-up will look like the following:
1: Tyus Jones
2: Rasheed Sulaimon
3: Matt Jones
4: Jabari Parker
5: Jahlil Okafor
Before you question my decisions, let me explain. For me, only the 5 is a certainty. I don't see any scenario, barring injury, in which Okafor doesn't start. Parker will start. And I believe he'll start at the 4 because his skillset is perfect for the 4: he can post up, take his man off the dribble, and has a decent jump shot. At the 3, Jabari doesn't have a reliable enough jumpshot. Also, if we have Amile Jefferson at the 4, that is three players from the 3-5 who are better in the paint then on the outside. And Coach K rarely, if ever, does that (Singler had a beautiful jumpshot. His outside game was 10x his inside game). Thus, it only makes sense that Jabari and Okafor are at the 4 and 5.
At the 1, it'll be Jones or Cook. Whoever has a) a better handle and b) better defense will get the nod. I don't think Coach K will start both as both are incredibly talented offensive players and not great defensively (at least what I've read about Tyus Jones). At the 2, I think it's Sulaimon. He is our best returning defensive player (not saying much) and second best returning offensive player (plus the best 3pt shooter).
And that leaves the last position. Given that we are stacked offensively at the 1, 2, 4, and 5, we need a defensive specialist. I went with Matt Jones because he has spent a year in the system and loves defense. He's a more talented Tyler Thornton with better height. If he can somehow find his jumpshot, that would be a pleasant surprise. This position could also go to Justise Winslow if he is better than Matt Jones at D.
Bottomline, with a rotation of 2 superstar freshman (unknown D but probably not great D), 1 senior with a great handle, reliable shot, and terrible D (Cook), 2 juniors who are decent at D but not great (Sulaimon and Jefferson), 1 man-child who hopefully improves on all fronts (Semi), and the most gifted offensive player in the country but has the reverse talent on D (Jabari), Winslow/Matt Jones will combine to play many, many minutes.
You think Coach K is going to have 2 inept defensive years in a row? He'll start at least one defensive-minded player.
